Australian energy company Santos has discovered a new gas resource in the Corvus field offshore Western Australia by drilling the Corvus-2 well.
Located at the petroleum permit WA-45-R, the well is around 90km northwest of Dampier in Commonwealth waters at water depths of 63m.
Reaching a total depth of 3,998m, the well intersected a gross interval of 638m making it one of the largest columns to have been discovered across the North West Shelf.
Wireline logging confirmed 245m of net hydrocarbon pay across the target reservoirs in the North Rankin and Mungaroo formations.
Initial pressure sampling completed in the well indicates that Corvus-2 encountered higher permeability zones compared to Corvus-1, which is situated 3km south-west of Corvus-2. Samples acquired from Corvus-2 also indicate a higher condensate gas ratio of up to ten barrels per million standard cubic feet of gas, significantly higher compared to Corvus-1.
Santos managing director and CEO Kevin Gallagher said: “Corvus-2 has delivered a fantastic result and has opened up a number of additional exploration opportunities in the region.
“It is particularly exciting to have realised a higher liquids content and significantly bigger resource volume than we expected.”
Corvus-2 is situated around 28km from the Reindeer platform and 62km from the Varanus Island tie-in point. The Corvus-2 well was drilled using Noble Tom Prosser, a jack-up mobile offshore drilling unit.
Gallagher added: “Corvus could be tied back to either our Devil Creek or Varanus Island gas plants, where it has the potential to increase the utilisation of our existing facilities as well as provide backfill and extend plateau well into the 2030s.”
